'Texas Killing Fields' Trailer: Sam Worthington, Jessica Chastain Star (VIDEO)

In their upcoming drama, "The Debt," Sam Worthington and Jessica Chastain take on both Israeli and slightly affected German. In their next film together, they trade those modulations in for a Texan-southern drawl. Which is particularly impressive for the Australian Worthington.

The pair -- who joked with the Huffington Post that they have a "five picture deal" together -- star in the upcoming "Texas Killing Fields," based on the true story of two cops who find that a murder they're investigating is connected to a long string of killings that, as the name implies, take place in a field. The film also stars Chloe Moretz, who plays a tough kid who may be the next victim.

The film hits theaters on October 7th.
